A common problem for Amazon Firestick users is that it gets stuck at a screen that says “Optimizing system storage and applications.” In some cases, the message never goes away and will not allow you to use the Firestick. We’ll cover what this message means and how to fix it in this guide.
Clearing the Error
If the message has been on your screen for longer than 10 minutes, you may want to try simply restarting the Firestick. You can do this by pressing and holding the “Select” and “Play/Pause” button simultaneously for about 15 seconds, or by simply unplugging then re-plugging the power cable on the Firestick.
Ensure Proper Power
I know this may seem odd, but if you experience the “Optimizing” message multiple times, the problem is probably caused by the Firestick not getting enough power. Most likely, you are using the USB port on your TV to supply power your Firestick.
Even though you may have previously been able to use your Firestick in this fashion, you can still run into problems. The USB port on your TV isn’t supplying the power needed.
To avoid this problem, plug the Fire TV directly into a wall outlet using a power block. Also be sure that you are using a power block that will send enough power to the device.
All generations of the Firestick utilize these specs for the power supply: 5.25V, 1A, 5W
Most laptop power adapter blocks send enough power and can safely be used with your Firestick.
I hope this post has helped you solve the problem where you Firestick keeps optimizing. Let me know if you need additional help in the comments.
